DETAILED DESCRIPTION

[0034] The following will be described in detail in combination with the drawings Figures 1-6 The application will be further described in detail.

[0035] In a first aspect, the embodiments of the application disclose a municipal cellar protection sleeve, which comprises a ring body and a manhole cover seat. Figure 1As shown, the structure includes a ring body 1 and reflectors 151. After the base layer 41 is laid, the ring body 1 is coaxially fitted onto the circular manhole cover seat 4, with the lower side of the ring body 1 in contact with the surface of the base layer 41. The height difference between the surface of the base layer 41 and the upper edge of the manhole cover seat 4 is approximately 4 cm, and the thickness of the ring body 1 is equal to this difference. A transition slope 14 is formed on the ring body 1. The cross-section of the ring body 1 is a right-angled triangle, and the transition slope 14 is the face containing its hypotenuse. The slope of the transition slope 14 slopes towards the side away from the manhole cover seat 4. The transition slope 14 serves as a transition slope around the manhole cover seat 4, ensuring that the ground structure consisting only of the base layer 41 allows for smooth traffic flow. The ring body 1 is made of rubber. Multiple reflectors 151 are provided. Mounting slots 15, with the same shape and number as the reflectors 151, are formed on the ring body 1 and on the slope of the transition slope 14. Each mounting slot 15 is used to embed one reflector 151, and all mounting slots 15 are evenly distributed around the ring body 1.

[0036] like Figure 1 , 2 As shown in Figure 3, the circular manhole cover seat 4 has three standard sizes: 800mm, 700mm, and 600mm (diameter). The ring body 1 is manufactured using the 800mm manhole cover seat 4 as a single standard, meaning the ring body 1 can be directly fitted onto the 800mm diameter manhole cover seat 4. For the other two smaller sizes of manhole cover seats 4, this solution uses a cutting device to cut the ring body 1 into sections, which are then spliced ​​together to form a smaller ring body 1. This smaller ring body 1 includes multiple sub-ring segments 11, arranged in a ring around the manhole cover seat 4. Each sub-ring segment 11 has a locking block 12 at one end and a locking groove 13 at the other end for the locking blocks 12 of adjacent sub-ring segments 11 to be inserted. In this embodiment, there are four sub-ring segments 11, and the projection shapes of the locking grooves 13 and locking blocks 12 along the axial direction of the ring body 1 are both T-shaped. When the four segments 11 are spliced ​​together to form a smaller ring 1, the shape of the new ring 1 is not a standard circle. After the new ring 1 is fitted onto the manhole cover seat 4, the inner side and edge of the ring 1 are tangent to the outer edge of the manhole cover seat 4, and four gaps are formed between them. Sand and gravel can be filled into these gaps to improve the overall flatness.

[0037] Secondly, this application discloses a cutting device for the aforementioned municipal manhole protective sleeve:

[0038] Example 1:

[0039] like Figure 2 , 4As shown in FIGS. 1-5, the cutting device comprises a placing mechanism 2 and a cutting mechanism 3. The placing mechanism 2 comprises a placing table 21 and a positioning assembly 22. The placing table 21 is used for placing the ring body 1. The positioning assembly 22 comprises a plurality of positioning blocks 221. Each positioning block 221 is fixedly connected to the table top of the placing table 21 and arranged in a ring shape. When the ring body 1 is placed on the placing table 21, the axis of the ring body 1 is perpendicular to the table top of the placing table 21. Each positioning block 221 is in contact with the lateral side of the outer edge of the ring body 1, so as to limit the lateral movement of the ring body 1. The cutting mechanism 3 comprises a forming blade 31, a cutting sliding block 34, a cutting sliding cylinder 33, a fixed ring plate 32 and a reset tension spring 35. The fixed ring plate 32 is separated from the placing table 21. The cutting sliding cylinder 33 is fixedly connected to the fixed ring plate 32, and the length direction of the cutting sliding cylinder 33 is parallel to the axis of the fixed ring plate 32. The cutting sliding block 34 slides in the cutting sliding cylinder 33. One end of the reset tension spring 35 is fixedly connected to the cutting sliding cylinder 33, and the other end is fixedly connected to the cutting sliding block 34. The forming blade 31 is fixedly connected to the side of the cutting sliding block 34 away from the reset tension spring 35. The cutting edge of the forming blade 31 is in a T shape.

[0040] As shown in FIGS. 1-5, Figure 2 , 4 The plate surface of the fixed ring plate 32 is provided with a positioning groove 321. The groove opening of the positioning groove 321 is consistent with the direction of the cutting edge of the forming blade 31. In the embodiment, the number of the positioning blocks 221 is consistent with the number of the positioning grooves 321, and the cross-sectional shape of the positioning blocks 221 is consistent with the cross-sectional shape of the positioning grooves 321. The fixed ring plate 32 is placed above the ring body 1, the groove opening of the positioning groove 321 faces downward, and the fixed ring plate 32 is lowered so that each positioning block 221 is inserted into each positioning groove 321. When the positioning block 221 abuts against the groove bottom of the positioning groove 321, the fixed ring plate 32 is coaxial with the ring body 1, and in the natural state, there is a gap of about 1-2 cm between the cutting edge of the forming blade 31 and the ring body 1. The operator needs to use a straight rod or other tools to insert the cutting sliding cylinder 33 from the side of the fixed ring plate 32 away from the placing table 21, push the cutting sliding block 34 to move downward, and until the forming blade 31 completes the cutting of the ring body 1. Since the number of the split ring segments 11 is four, and the size of the manhole cover seat 4 that needs to be cut by the ring body 1 is two, the fixed ring plate 32 has two, the number of the cutting sliding cylinders 33 fixed on a single fixed ring plate 32 is eight, and the spacing of the cutting sliding cylinders 33 on the two fixed ring plates 32 is different, that is, different fixed ring plates 32 correspond to different sizes of the ring body 1 to be cut.

The cutting mechanism 3 further comprises a fixed-length template 36, which is used to indicate the position that needs to be pressed for the operator when cutting the ring body 1, so that the fixed-length template 36 is provided with operation holes 362 penetrating through the thickness of the plate, and the fixed-length template 36 is two, the number of operation holes 362 on a single fixed-length template 36 is eight, and the distance between the operation holes 362 on the two fixed-length templates 36 is different. The fixed-length template 36 is circular, and after the fixed-length template 36 is coaxially placed on the side of the fixed ring plate 32 away from the placement table 21, the eight operation holes 362 are respectively aligned with and communicated with the eight cutting slide cylinders 33, at this time, the cutting slide block 34 exposed at the operation hole 362 is the cutting position that needs to be pressed by the operator.

[0043] As shown in FIGS. 6, the difference between the first embodiment and the present embodiment is that the fixed ring plate 32 is only one, and the number of cutting slide cylinders 33 connected to the fixed ring plate 32 is sixteen, in which eight correspond to the cutting of the ring body 1 of the well lid seat 4 with a size of 700 mm, and the other eight correspond to the cutting of the ring body 1 of the well lid seat 4 with a size of 600 mm. The cutting mechanism 3 further comprises a fixed-length template 36, which is used to indicate the position that needs to be pressed for the operator when cutting the ring body 1, so that the fixed-length template 36 is provided with operation holes 362 penetrating through the thickness of the plate, and the fixed-length template 36 is two, the number of operation holes 362 on a single fixed-length template 36 is eight, and the distance between the operation holes 362 on the two fixed-length templates 36 is different. The fixed-length template 36 is circular, and after the fixed-length template 36 is coaxially placed on the side of the fixed ring plate 32 away from the placement table 21, the eight operation holes 362 are respectively aligned with and communicated with the eight cutting slide cylinders 33, at this time, the cutting slide block 34 exposed at the operation hole 362 is the cutting position that needs to be pressed by the operator. Figure 6 As shown in FIGS. 6, the difference between the first embodiment and the present embodiment is that the fixed ring plate 32 is only one, and the number of cutting slide cylinders 33 connected to the fixed ring plate 32 is sixteen, in which eight correspond to the cutting of the ring body 1 of the well lid seat 4 with a size of 700 mm, and the other eight correspond to the cutting of the ring body 1 of the well lid seat 4 with a size of 600 mm. The cutting mechanism 3 further comprises a fixed-length template 36, which is used to indicate the position that needs to be pressed for the operator when cutting the ring body 1, so that the fixed-length template 36 is provided with operation holes 362 penetrating through the thickness of the plate, and the fixed-length template 36 is two, the number of operation holes 362 on a single fixed-length template 36 is eight, and the distance between the operation holes 362 on the two fixed-length templates 36 is different.

[0044] The implementation principle of the municipal cellar protection sleeve and the cutting device according to the present embodiment is as follows:

[0045] For the size of 800 mm well lid seat 4, the ring body 1 is directly fitted outside the well lid seat 4, and for the size of 700 mm or 600 mm well lid seat 4, cutting device needs to be used for cutting, and different fixing ring plates 32 or fixed size templates 36 are used for different sizes. After cutting, the original ring body 1 is divided into four ring segments 11 and four waste materials. After removing the four waste materials, the four ring segments 11 are spliced into a new ring body 1. Since the contour of the new ring body 1 is not a standard circle, after the new ring body 1 is fitted outside the well lid seat 4, the outer edge side wall of the well lid seat 4 is tangent to the inner side edge of each ring segment 11, and four gaps are formed between the two, which need to be filled with sand and stone to improve the overall flatness.

[0046] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
